Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, and more specifically to a molding mold for drawer production. Background Art

[0002] Plastic storage drawers are common daily necessities and are generally mass-produced using injection molding molds.

[0003] Based on the above, the inventors have discovered that when a traditional molding mold is used to produce drawers, the molten material is usually injected into the cavity formed between the male mold core and the female mold core through the injection molding part, the material is cooled and formed, and then the demolding operation is performed. However, since the structure of the male mold core and the female mold core is mostly integrated, a number of ejector pins are required to assist in demolding, and the control operation of the ejector pins is relatively inconvenient, which can easily cause certain damage to the molded drawer product, resulting in an increase in the scrap rate of the molded product, affecting its product quality and production efficiency. Therefore, in view of this, the existing structure is studied and improved, and a molding mold for drawer production is provided, in order to achieve a more practical purpose. Utility Model Content
